Definition

A material property defined as the ratio of uniaxial tensile (or compressive) engineering stress to engineering strain within the linear elastic region of the stress–strain curve; numerically E = σ/ε for small strains, with SI units pascal (Pa).

Definition

Young's modulus (E) is the linear elastic constant that equals the ratio of uniaxial axial (normal) stress to axial (engineering) strain for a homogeneous material in the small‑strain, linear elastic regime: σ = E·ε. It quantifies a material's stiffness in tension or compression under uniaxial loading and is expressed in pascals (Pa).
